Tendons are primarily composed of Type I collagen, and Vitamin C, proline, and glycine are key raw materials for resynthesis after damage. Excessive sugar intake interferes with collagen cross-linking through the formation of Advanced Glycation End Products (AGEs), while alcohol inhibits blood flow and protein synthesis within the tendons. Omega-3s (EPA and DHA) help alleviate chronic inflammation in tendons by inhibiting the COX-2 pathway. Korean Medicine Clinic Perspective In Korean medicine, the relationship between food and tendon health is explained through digestive function. Smooth digestion and absorption are essential for sufficient nutrient delivery to muscles and tendons. Greasy and cold foods generate waste products in the body, impairing digestive function and blocking the circulation of Qi and blood. Dongjedang promotes both digestive function and blood replenishment simultaneously through herbal medicine tailored to individual constitutions, and provides guidance on lifestyles through dietary counseling to prevent the accumulation of waste products and stagnant blood.
